Krupa Ramasesha named Fulbright US Scholar
News Article, August 14, 2025 • The Department of State named chemist Krupa Ramasesha to the Fulbright U.S. Scholar Program to Austria for the 2025-2026 academic year. During her time in Austria, Krupa will hold the Fulbright-NAWI Graz Visiting Professorship in the Natural Sciences at the Institute of Experimental Physics at Graz University of Technology. In this position,...

Molecular monolayers control ultrafast charge and heat transfer in gold for plasmonic applications
News Article, August 24, 2026 • Sandia researchers explore how energy and charge move on ultrafast time scales between gold nano-islands and a single layer of 4-mercaptobenzoic acid (4MBA) molecules attached to their surface, a process at the core of emerging technologies like plasmonic sensors and photocatalysts, which have clear national-security implications for chemical detection and...

Sandia researchers examine chemistry in areas that help improve the safety, reliability, and performance of technologies involved in national security
News Article, August 24, 2026 • Sandia researchers examined how “cold” electrons, which have very little energy, can cause certain molecules made of nitrogen and oxygen such as N₂O₃ and N₂O₄ to break apart. These molecules are important to chemistry that occurs in high‐energy environments such as plasmas, combustion chambers, and atmospheric re-entry flows. Examining the...
